My understanding is that Liverpool pilot Philip John Holt TEBAY was born 1928 in Wallasey, son of another Liverpool pilot Cecil Hugh Forrest TEBAY (b1885 London) who perished (along with my relative Thomas Ledsham EVANS) in the CHARLES LIVINGSTON incident in November 1939.
Cecil was a son of William Holt TEBAY (b1857 Poynton Cheshire), he a son of Septimus TEBAY (b1836 Winstanley, Lancashire), he a son of Thomas TEBAY who married Margaret SHAW on 4 December 1826 in All Saints Church, Wigan.
The name is relatively rare, so there's a good chance your female TEBAY might belong to the same family.
